The article doesn't contain much new information for hard core fans of Avatar, but it does mention a few interesting items such as air bison being the original airbenders.

Also, the creators dealt once again with the issue of season three being the last season of Avatar. From the interview:

IGN: What can we expect for Avatar's third season? Will this season be the final installment to the Avatar world?

MIKE: This particular, three season arc will end in an exciting way that wraps up the story of Aang and Zuko. However, Bryan and I have other ideas to expand the Avatar universe, so hopefully the world will live on for a long time.
